A packaging for transporting in emergence living fish the pleuronectiform species, includes at least one box (1) opening from above and whose bottom is provided with an active surface (2) for receiving the fish to be packaged in flat position. The support active surface (2) for the fish consisting of ventilated solid (3) and void (4), the solid (3)/void (4) ratio of the active support surface (2) ranging between 0.25 and 9 to provide an efficient cutaneous respiration to the fish support surface...

An animal collar particularly adaptable to cats has a permanent magnet fastener which is smooth and free of projections when coupled. The fastener embodies interfitting sections which are easy to engage and separate by a simple pushing and pulling operations. Conventional buckle hardware is completely eliminated. The collar will open under a predetermined load in the event that the animal becomes hung or caught on a tree, fence post, or the like.

A fish rearing system having a water circulation system comprising: a trapping section including a particle trap 2 for capturing residual feed and fish feces contained in the water, a sediment trap 6 for accumulating a sediment in a rearing tank and separating the sediment from the water, a residual feed detecting sensor 5 interposed in a pipe 4 communicating with the particle trap 2 and the sediment trap 6, and a micro-screen filter 7; a denitrification device 12 for denitrifying a nitrogen com...

A water-dispersible hybrid polymer of a core/shell structure is provided which is based upon (A) a polymer (core) of a mercapto-functionalized poly(epoxyester) onto which (B) at least one addition polymer-based chain (shell) has been grafted via the addition polymerization of free-radically polymerizable monomers in the presence of the mercapto-functionalized poly(epoxyester). Also provided are aqueous dispersions of these hybrid polymers and coating compositions therefrom, which coating composi...

A system and process is described for treating the effluent chemicals from an air pollution control system for fossil fuel fired equipment. The air pollution control system involves the addition of magnesium-containing additives such as dolomite to the equipment followed by the wet scrubbing of the flue gases resulting in the reaction of the sulfur oxides with the additive. The treatment involves the addition of ammonium hydroxide to the solution removed from the scrubber to convert the soluble ...

An x-ray radiator has an x-ray tube disposed in a protective housing and a fastening means having a portion attached to the x-ray tube inside the housing, and a portion which extends through the housing to the exterior of the housing. The exterior portion serves as a fastener to attach the x-ray radiator to a mount. The x-ray tube, within the housing, thus becomes directly attached to the exterior mount, which improves the precision with which the specified position of the central ray of the x-r...

The collection of aquatic animal eggs during hatchery production is a critical step in the successful rearing of these animals. Currently, the equipment and culture methods do not allow large numbers of animals to be spawned at the same time without several people handling the process. The disclosed invention solves the problem of collecting large quantities of released aquatic animal eggs after spawning many adults at the same time. The apparatus is simple to build, maintain, and repair, and th...

Compounds of the formula: ##STR1## wherein the substituents are as defined herein, and enantiomers, diastereomers, racemates and salts with pharmaceutically acceptable bases, antagonize LTD.sub.4 action and thus, are useful in treating bronchial asthma, pulmonary anaphylaxis, cystic fibrosis, chronic bronchitis, bronchiectasis, respiratory distress syndrome and pulmonary oedema.

A D.C. lamp system having a number of small zener diodes arranged in eleccal parallelism with various lamp current supply wires. The zener diodes are sized so that the collective wattage ratings of the zeners is equal to the arithmetical product of the D.C. supply voltage and the summation of the safe amperages of the lamps in the system. In event of normal lamp burnout, any tendency of the other lamps to also burn out due to excessive current surge is countered by the action of the zener diodes...

A process for extracting hydrogen fluoride from fluorine containing materials includes countercurrently contacting the materials with steam having a plane of rotation relatively perpendicular to the direction of flow of the material. An apparatus for the extraction of hydrogen fluoride from fluorine containing materials includes a rotary kiln having a first zone wherein a steam-air mixture countercurrently contacts the materials in an oxidation step, a second zone wherein an oxygen containing ga...
